Etude histo-pathologique de la chorio-retine des prematurés

Résumé Les auteurs ont étudié au point de vue anatomo-pathologique le segment postérieur de 38 globes de prématurés. Ils ont observé des altérations diverses: laxité de coaptation des deux feuillets rétiniens, anomalies vasculaires, lésions de la membrane limitante intéressantes par leur valeur pathogénique dans le cadre de la fibroplasie rétrocristallinienne.

Summary The authors examined histologically 38 eyes of premature newborns. Different alterations were observed: lax coaptation of the two retinal layers, vascular anomalies, lesions of the limitant membrane, which may be of some interest in connection with retrolental fibroplasia.

Septo-optic dysplasia (de Morsier syndrome).

A 12-year-old girl and a 30-year-old woman had bilateral optic disk hypoplasia and bitemporal hemianopia. By using computed axial tomography on our patients, we demonstrated the absence of the septum pellucidum, which confirmed the diagnosis of septo-optic dysplasia, or the de Morsier syndrome.     

Persistencia bilateral de la arteria hialoidea. Reporte de un caso

Case reportA 5-year-old male presented with bilateral poor vision, esotropia and a previous diagnosis of cataract since he was 1 year old. The physical examination revealed bilateral posterior paracentric capsule opacification, vitreous cavity with a permeable pulsatile blood filled hyaloid artery in both eyes. He was kept under observation.DiscussionPersistent hyaloid artery is an uncommon faulty primary vitreous regression, often unilateral (although it may be bilateral) and sporadic, associated with microphthalmos. It may be complicated with glaucoma and phthisis bulbi. Vitrectomy plus lensectomy or simple observation are the accepted treatment options.
